The search effort for a man missing on Lake Lanier since Friday continued Saturday night, officials said.

Mark McKinnon, a spokesman with the Department of Natural Resources Law Enforcement Division, said crews were continuing the search with sonar after dark Saturday and would do so well into the night.

The name of the victim has yet to be release.

Law enforcement crews responded to the call Friday evening. Forsyth County dive teams requested assistance from Hall County Fire Services in the operation.

Forsyth County Fire Investigator Jeff Hundley said the incident was reported to be about 300 yards off shore near Vann's Tavern Park, in water just over 125 feet deep. Hundley said he believed there were witnesses who saw the victim, identified as an adult male, in the water before he went under.

This drowning is less than a week after the last one, which also happened near Three Sisters Island. Officials searched for that victim, 23-year-old Kevin Theodore Husum, of Panama City, Fla., for most of the week, but were unable to locate him.
